[THIN] Typing Latency

Well we are at our wits end with this one and looking for some advice…….

 

First our background: 

Windows 2003 Enterprise Server with SP2 - 32 BIT

Xenapp 4.0 with R04

Compaq C Series blades, Dual Quad Core Proc with 16 GB RAM, NICS are attached GB connection

Clients are connecting with the newest Full PN ICA Client 10.2 through Web Interface 4.5

 

We are experiencing typing delays and some random disconnects.  Session Reliability is kicking in from time to time with some session disconnects.  We have opened a case with Citrix and checked the normal stuff such as Network QOS traces, perfmon traces, and speedscreen settings to no avail……Clients are hard wired to the dual T1 network and the SMC traces appear clean even while the issue is occurring……Norton AV is installed on the workstations and Citrix Servers but real time scanning is disabled on the Citrix Servers and a nightly scan is conducted at 2:00 AM….Servers are rebooted weekly as well…..

 

Any ideas?
